I just use a (dry) brush to clean them during the round...maybe not after every shot, but more often with the wedges. It's rare that I need more than a dry brush, if I do I just squirt a little water out of my water bottle directly onto the club.
That was exactly what I was trying to accomplish. The "myth" that occurred to me as I was driving nearly the full length of the PA Turnpike this morning (and saw a trooper about every 10 miles) was the idea that State Police have a monthly ticket quota, and you're more likely to get a ticket at the end of the month.
I would love this, but it is the same weekend as the Pittsburgh/Ohio TST outing.
You should join in on that (it is Saturday).
